Start Preamble
AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule.
SUMMARY:
The FAA is superseding Airworthiness Directive (AD) 2020–07–13, which applied to certain Bombardier, Inc., Model BD–100–1A10 airplanes. AD 2020–07–13 required revising the existing airplane flight manual (AFM) to provide the flightcrew with new warnings for “Autoflight” and “Engine Failure in Climb During ALTS CAP.” This AD requires revising the existing AFM to provide the flightcrew with new warnings for “Autoflight” and “Engine Failure in Climb During (V) ALTS CAP or (V) ALTV CAP.” This AD was prompted by a revision to the procedures to ensure that all applicable altitude capture modes utilized and annunciated in the affected fleet are included and to more clearly denote these altitude capture modes. The FAA is issuing this AD to address the unsafe condition on these products.
DATES:
This AD is effective August 7, 2023.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 7, 2023.

End Further Info End Preamble Start Supplemental InformationSUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2020–07–13, Amendment 39–19892 (85 FR 20394, April 13, 2020) (AD 2020–07–13). AD 2020–07–13 applied to certain Bombardier, Inc., Model BD–100–1A10 airplanes. AD 2020–07–13 required revising the existing AFM to provide the flightcrew with new warnings for “Autoflight” and “Engine Failure in Climb During ALTS CAP.” The FAA issued AD 2020–07–13 to address the occurrence of an engine failure during or before a climb while in ALTS CAP or (V) ALTS CAP mode, as it could cause the airspeed to drop significantly below the safe operating speed and may require prompt flightcrew intervention to maintain a safe operating speed.
The NPRM published in the Federal Register on April 10, 2023 (88 FR 21123). The NPRM was prompted by Start Printed Page 42610 AD CF–2019–12R1, dated June 9, 2022, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that during altitude capture flight, the flight guidance/autopilot does not account for engine failure while capturing an altitude. The MCAI states that Transport Canada AD CF–2019–12, dated April 3, 2019, referenced specific altitude capture modes but did not consider all possible available annunciated altitude capture modes used in the affected airplanes. Therefore, the MCAI mandates further updates to the Limitation and Emergency Procedures sections of the AFM to ensure that all applicable altitude capture modes utilized and annunciated in the affected fleet are included and more clearly denotes these altitude capture modes in these new procedures.
In the NPRM, the FAA proposed to require revising the existing AFM to provide the flightcrew with new warnings for “Autoflight” and “Engine Failure in Climb During (V) ALTS CAP or (V) ALTV CAP.” The FAA is issuing this AD to address the occurrence of an engine failure during or before a climb while in altitude capture flight. The unsafe condition, if not addressed, could cause the airspeed to drop significantly below the safe operating speed and may require prompt flightcrew intervention to maintain a safe operating speed.
You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–0662.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of the cost to the public.
Conclusion
This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed the following service information, which provides new warnings for the “Autoflight” procedure in Section 02–04, “Systems Limitations,” of the LIMITATIONS section; and “Engine Failure in Climb During (V) ALTS CAP or (V) ALTV CAP,” procedure in Section 03–32, “Powerplant,” of the EMERGENCY PROCEDURES section; of the applicable AFMs.
- Bombardier Challenger 300 Airplane Flight Manual (Imperial Version), Publication No. CSP 100–1, Revision 69, dated July 4, 2022. (For obtaining the procedures for Bombardier Challenger 300 AFM (Imperial Version), Publication No. CSP 100–1, use Document Identification No. CH 300 AFM–I.)
- Bombardier Challenger 350 Airplane Flight Manual, Publication No. CH 350 AFM, Revision 34, dated June 14, 2022. (For obtaining the procedures for Bombardier Challenger 350 AFM, Publication No. CH 350 AFM, use Document Identification No. CH 350 AFM.)
These documents are distinct since they apply to different airplane models in different configurations. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.
Costs of Compliance
The FAA estimates that this AD will affect 244 airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 $0 $85 $20,740 Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
Regulatory Findings
The FAA determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a “significant regulatory action” under Executive Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
